One dose of COVID-19 vaccine provokes strong immune response in those previously infected

Although clinical trial data are encouraging, real-world evidence with regard to the COVID-19 vaccine remains scarce. In particular, response to the vaccine among those previously infected with SARS-CoV-2 is still not completely understood.

Researchers from Bar-Ilan University and Ziv Medical Center now report preliminary evidence that people previously infected with the virus responded very strongly to one dose of the Pfizer vaccine, regardless of when they were infected and whether or not they had detectable antibodies against COVID-19 prior to receiving the vaccine.

Scientists urge for investment now in highly potent vaccines to prevent the next pandemic

As new COVID-19 variants begin to throw vaccine efficacy in question, two leading scientists are calling for health agencies to invest in the development of vaccines that would be broadly effective against many different variants and strains of potential pandemic viruses.

In a commentary article published in the journal Nature, Dennis Burton, PhD, and Eric Topol, MD, of Scripps Research call for governments to provide significant funding support for rational vaccine design based on broadly neutralizing antibodies.

Anticancer drug may improve outcome for severe COVID-19 patients

Treating severe COVID-19 patients with the anticancer drug bevacizumab may reduce mortality and speed up recovery, according to a small clinical study in Italy and China that was led by researchers at Karolinska Institutet in Sweden between February and April 2020. On average, blood oxygen levels, body temperature and inflammatory markers significantly improved in patients treated with a single dose of bevacizumab in addition to standard care.

Novel molecules to combat asthma and COVID-related lung diseases discovered

A study designed to study how the immune system impacts gut bacteria - has led to the extraordinary discovery of two molecules that can not only provide profound protection in experimental models of asthma but can also substantially reduce the severity of an attack.

Neither of these molecules, one of which is already commercially available as a dietary supplement, were previously known to have an effect on asthma - and they also appear, from animal studies, to have a role in treating the respiratory illness that is prevalent, and often fatal, in people with serious COVID-19.

Obesity, impaired metabolic health and COVID-19

In a Nature Reviews Endocrinology article authors from the German Center for Diabetes Research (DZD) highlight the interconnection of obesity and impaired metabolic health with the severity of COVID-19. First, they provide information about the independent relationships of obesity, disproportionate fat distribution and impaired metabolic health with the severity of COVID-19.

COVID-19 has multiple faces

According to current studies, the COVID-19 disease which is caused by the SARS-CoV-2 coronavirus comprises at least five different variants. These differ in how the immune system responds to the infection. Researchers from the German Center for Neurodegenerative Diseases (DZNE) and the University of Bonn, together with other experts from Germany, Greece and the Netherlands, present these findings in the scientific journal "Genome Medicine".

Metformin use reduces risk of death for patients with COVID-19 and diabetes

Use of the diabetes drug metformin - before a diagnosis of COVID-19 - is associated with a threefold decrease in mortality in COVID-19 patients with Type 2 diabetes, according to a racially diverse study at the University of Alabama at Birmingham. Diabetes is a significant comorbidity for COVID-19.
